The Pretensioner - How Seatbelts Work | HowStuffWorks

Apr 09, 2002 · The Pretensioner. When the gas is ignited, the pressure pushes the piston up to rotate the retractor. The idea of a pretensioner is to tighten up any slack in the belt webbing in the event of a crash. Whereas the conventional locking mechanism in a retractor keeps the belt from extending any farther, the pretensioner actually pulls in on the belt.
